Privacy policy

The short version: Guitarry’s practice material stays on your computer. There is no Guitarry account or login. Camera and tuner input are processed locally and are not uploaded. A Pro license key is checked through guitarry.com and Lemon Squeezy so paid features can unlock.

What the desktop app stores

The desktop app stores settings, locally created tabs, saved practice sessions, instrument preferences, the date your free trial started, and—if you activate Pro—the license key, activation identifier, device credential, entitlement status, and last validation time in its local application-data folder — the key and the credential encrypted so that a copy of the folder is useless on another computer. So the free trial cannot be restarted by deleting that folder, a copy of the trial-start record—a date and a random identifier, nothing personal—is also kept in a small second folder on the same computer (see Delete your data). Guitarry does not upload your tabs, saved sessions, camera video, or tuner audio, and the trial record never leaves your machine.

The app has no Guitarry user account, shows no ads, and does not track you across other apps or websites.

Microphone

The microphone is used by the built-in tuner. While the tuner is listening, audio is analyzed on your computer in real time to estimate pitch. The tuner audio is not recorded, stored, or transmitted. The desktop Pro release does not use microphone audio to grade practice.

Camera

The camera is processed on your computer to find and track the guitar fretboard and draw overlays selected by you. Camera frames are not uploaded or retained by the desktop app. This release does not analyze fingertips or grade playing.

Purchases and license checks

Guitarry Pro for desktop is sold through Lemon Squeezy, our merchant of record. Lemon Squeezy collects and processes the checkout information needed to take payment, issue receipts and license keys, prevent fraud, handle tax, and manage the subscription. Guitarry does not receive your full payment-card details.

When the app activates or validates a key, it sends the license key, an identifier for this installation, a device credential, and a short computer label through guitarry.com to Lemon Squeezy’s License API. Guitarry stores the resulting entitlement locally.

Because one purchase covers one active computer, guitarry.com also keeps a small record of which installation currently holds a license. That record contains a one-way SHA-256 digest of the license key, the installation identifier, the Lemon Squeezy activation identifier, a one-way digest of the device credential, and the times it was created, changed, and released. It does not contain the license key itself, the device credential itself, or your email address.

The first activation of a license requires a six-digit code, which we email to the address Lemon Squeezy holds for that purchase — never to an address typed into the app. While that code is live we keep a record containing a keyed one-way digest of the code, the same two identifiers as above, a masked hint of the address (for example ri···[email protected]), and its expiry and attempt count. The code itself and the full address are not stored. The record expires about ten minutes after it is issued, and is deleted or spent on use.

Our signed billing webhook records limited order and subscription status information—including the checkout email, product, variant, and total—in a private delivery database and our private operations sheet for support and reconciliation. Raw webhook payloads are not stored, because they can contain license keys.

Crash and usage reporting

The desktop app does not automatically send crash reports or usage analytics. If privacy-respecting website analytics are enabled, they may record aggregate page visits, referrers, and campaign parameters. They do not receive license keys, payment details, audio, video, names, email addresses, or free-text form answers.

Issue reports you choose to send

You can choose to send an issue report from the desktop app. A report contains the description and reproduction steps you enter, optional follow-up email, and—if you leave diagnostics enabled—the app page, app and operating-system versions, and camera-engine status. You can also choose screenshots or one short video to attach. Guitarry never adds a camera recording or imported tab automatically.

The report is stored in our private testing queue, attachments are kept in private cloud storage, and a notification is sent to [email protected]. We use this information only to reproduce, prioritize, and resolve the issue. A readable report copy remains on your device so it is not lost if delivery fails.

What the website collects

Earlier versions of guitarry.com offered a founding-list signup. If you joined it, we hold the details you submitted: email, optional name, playing experience, instrument type, phone type, practice pain, and testing interest. We use them to qualify beta testers and send relevant product updates, and you can ask us to remove them at any time (see Delete your data). The site no longer collects signups.

Delete your data

Uninstall Guitarry and remove its local application-data folder to erase its settings, license record, saved sessions, and local tabs from that computer. The trial-start record also lives in a second folder named after the app under your local application data (its trial subfolder); remove that too for a complete wipe—it holds a date and a random identifier, nothing personal. Deactivate the license in Settings → Subscription first if you want to free that activation for another computer — that also releases the one-device record described above. If the computer is already gone, email [email protected] from the address you bought with and we will release it.

For anything held outside the app—a founding-list signup, billing event, issue report and attachments, or support email thread—send a deletion request to [email protected]. Include the order or report ID if you have it.

Deleting local data does not cancel a subscription. Manage or cancel it through the Lemon Squeezy order portal linked from the purchase receipt, or email [email protected] for help.

Age

Guitarry is intended for people age 13 and older and is not directed to children under 13.
